Orion prioprietary EJB 1.1 OR mapping

This article describes how to Use Orion's proprietary OR-mapping for pre EJB 2.0 entity beans.

1 Step-by-step Guide

Go through the following steps to use Orions proprietary pre EJB 2.0 OR-mapping for entity beans:

Step 1: Create the fields
Step 2: Add a type-descriptor (optional)
Step 3: Redeploy

1.1 Step 1: Create the fields

Create the field that is to hold the relational mapping, common types are Collection, Set List and Map:

public Set items;

Listing 1: Example field

1.2 Step 2: Add a type-descriptor (optional)

Add a type-descriptor (optional, will simplify deployment), to identify the contents of the type:

public static final Class items_type = java.lang.String.class;

Listing 2: Example type-descriptor

or if it is of type Map:

public static final Class items_keyType = java.lang.String.class;
public static final Class items_valueType = java.lang.Integer.class;

Listing 3: Example type-descriptor

where "items" is the name of the field (public Set items; for instance).

1.3 Step 3: Redeploy

Redeploy, the OR-mapping should automatically be created.
